This thread is quite related to a question which this thread (to no suprise) causes me to think of.
Be Forewarned, what I have written will probably either make you say, "Ah yes, I understand", or "please", those undergoing anger management may want to ignore O_o
What is the percentage for the average pianist, would you estimate technique is required to conquer a piece quite well? Or even better, what is the recommended minimal percentage required for a piece you are going to learn?
Slightly more depth, which get's a bit messy: I have the technique to perform a piece note wise correctly, except I don't always hit them all. So in theory, having just learnt the technique to perform the piece won't cut it, you will need to progress this technique until it becomes reasonably "better" - Not sure that is the best word...
So... is there like an approximate percentage in relation to the piece's difficulty? I realise there is SOO many factors involved in this, but it's a tough one to not go with out knowing SOME sort of "Guideline" to help you pick the correct pieces to play, and not wasting your time figuring out trying to play it to see if your ready.
An Example for further clarification (or confusion) in a scenario of a computer game:
The C Major Scale Technique
With 0% Skill Points, you never performed any scale, let alone played on the piano!
With 1% Skill Points, you can *JUST* perform it with one hand, barely;15bpm.
With 40% SKill Points, you can perform it sometimes; 30bpm.
With 75% SKill Points, you can perform it quite well; 60bpm.
With 99% Skill Points, you can butt whoop it on the literal verge of perfect; 240bpm.
With 100% Skill Points, is this possible? Maybe, Theoretically.
When you learn a new piece, should you atleast have 30% (for example!) of each technique required, or elsewise you are wasting your time? (In terms of productivity with technique/repertoire aquisition etc.)
In theory you should be able to calculate this yourself to some extent. Me with the Rach3 is probably 1%, remember that's 1% in relation to the requirements of the Rach3, not the C Major Scale!

Well, Okay, I just confused everyone enough. For those of you who understand what I'm getting at, you'll probably think I'm wasting my time! Actually I'm beginning to wonder if spending all this time on this post is worth it, but hey, I'll give it a shot

It's just... Curiosity Killed The Cat (Or should I say the flames will).
